Use One Preset Per Batch
Choose one output format, quality value, and resize rule for all files in the batch. Mixed settings lead to inconsistent exports.
Process In Manageable Queues
Most browser-based tools support queues of up to 50 files. Split larger batches into multiple runs with the same preset.
Audit With Summary Manifests
A ZIP export with summary.json and summary.csv gives you a record of every file's original size, output size, format, and processing time.
